Other companies have offered proprietary media and I think it's fair to say that increases cost. BMD has tried to go with industry standards or create their own solution within the framework of industry standards. They could contract to a foundry to build CFast 2 cards to their own specifications, but in a way that is happening in that some of the industry is adapting their products to ensure it is compatible with this new generation of digital film cameras, examples are currently Digistor, Lexar, and now Wise. It's going to make the price of media fall. The LEXAR 3400x 256GB card is the same price now as the Sandisk 120GB card earlier this year.

How about a list of approved cfast 1.0 cards that are good for 1080...80fps??? I'm currently using my shuttle2 to record externally because I haven't needed to shoot in 4k...so, I've been able to forgo paying the current ridiculously overpriced cfast2.0 cards. That being said, I would much rather be recording internally for the many obvious reasons.I've read a few post regarding the atomos cards working fine, curious has anyone experimented with other brands???

Atomos card not working properly!!!On HD ProRes 422 25 fps I have drop frames and audio loses sync.Sometimes takes 40-50 minutes with no problems, while sometimes it starts droping frames after one minute.I have last firmware 2.0.

I don't imagine BM will approve any CFast 1.0 cards to be honest. From what I've read you can just about scrape by if you're shooting 1080p at low framerates under certain, specific conditions (i.e. right version of prores, right card formatting, etc), but it seems too patchy to be encouraged.

Using a 120GB SanDisk card shooting at 29.97 FPS HD, it suddenly crashed with about 60GB of data. The camera's firmware was version 2.0. I contacted SanDisk and the engineer a very helpful nice guy I may add, recommended to set the camera's firmware back to 1.9.10 when using the 120GB card.

The card has been returned to SanDisk for failure analysis. Fortunately, Sandisk will also try to recover the lost data. Needless to say, wonderful customer support by SanDisk.

I have a week-long production next week using both a 120GB and the new 128GB card. We'll see...

Thanks

Nothing fancy. 4k prores @24p. Still, I thought it was worth noting given the lack of information (and my obvious relief). Unfortunately, I won't be able to do any additional testing for atleast another week. Hopefully by then BM and others will have come to a conclusion.

Thanks! Anything and everything helps since these cards are pretty expensive and a decision on which to get is not to be taken lightly.

Do not use the Lexar CR1 USB 3.0 reader. We averaged a very unstable speed of 25mbs/sec. We looked up a lot of info on it. It seems others were having similar issues.

Cheers

I think Lexar realizes their CR1 product may not be up to snuff. They have a new product, CR2, that supports Thunderbolt2 and USB 3 "coming soon" according to B&H Photo. Costs more, but this could be the fastest reader available when it launches, and when it comes to workflow around these precious CFast 2 card, time is money.

Lexar also offers a HR2 hub (TB2/USB3) which has four slots for you to mix and match CR2s and DD512 flash storage units (store up to 512GB each, USB3). So your DIT could grab your CFast 2 cards, insert it into a CR2 (standalone or use a slot of the hub) and quickly offload via the HR2 hub to 2TB of portable storage for later transfer to your edit suite. I'm not a salesman, just I like these Lexar options.

Easy to mount 2 of them to a 4U or 5U ingest station, each gets it's own USB 3.0 connection, so 5Gb/s per card. That Lexar hub looks interesting, but I'd rather see the CR2's rackmounted 4 wide in a 1U face. I know a lot of users will want a desktop dock, but for DIT racks, it's not ideal.

I'm a bit surprised that SATA3 docks for CFast aren't around. I figured they would be perfect matches.

I have the same question about the Lexar 64GB cards. I know the 32GB ones have much lower write speed, but the 64GB cards are listed by Lexar as having the same write speeds as the 128GB and 256GB cards.

I received my C-Box system that allows me to use my SSD Drives with the C-Fast cards slots on the URSA Mini. The unit is extremely sturdy. I placed the SSD Drives in the unit and tried to shake them out, but the wouldn't bulge... I'm using two 1TB hard drives from digistor.

Although not quite the same as being on the BMD CFast 2 certified list, the Lexar compatibility list has proven accurate with regard to the new 3600x card. Someone on BMCuser acquired the card after having dropped frames on the 3400x card and the 3600x card performed flawlessly.

I just saw a review of the C-box system and it seems like a very good option for even the highest frame rates with the URSA and URSA mini. At one time you could buy it for $325 on the kickstarter campaign, but it's now $500 on the website. Has anyone used the C-box for an actual production and if so...please post your results. Yes...it's another thing to mount on your camera, but non drop frames and non compressed media transfer rates pretty high it seems like a very good option.

Thoughts?

I've heard nothing but amazing results, recently ordered one. Waiting for it to arrive. Willing to share my thoughts when it comes - as well as a comparison to my wise cfast cards which I've had no problem with so far.

Thank god for the 3600x working flawlessly for that user. I assumed it was okay because I saw it was compatible on the Lexar site, but I had not seen it on the BMD forums. Hopefully thats the case!

Is there are list anywhere yet that explains what cards are needed to shoot UHD 60 frames in ProRes444? All the BMD support info and manuals say is "shooting up to 30 frames per second 4K raw". Looking at the data rates, it appears that UHD ProRes444 in 60 frames is more data. So which cfast card will support it?

Yes ... it would be very helpful to know about the Lexar 3600x cards. The Lexar post indicate that it is approved. I would like to know for sure before I open up the two Lexar 3600x cards I ordered a while back. My 4.6k arrives tomorrow, and it would be nice to take it out for a spin. The Lexar 256GB 3400x have been discontinued. Some are available from China ...but.

I worry about spending all that cash on the x3600s to have them still drop frames.

With the pocket camera I laid out for the priciest legit Sandisk Extreme Pro SD cards on BM's official supported list and was burned when they still dropped frames in ProResHQ for nearly the first full year of use until BM finally ironed out the issue in the camera firmware. I realize that was a different camera, but you never know until you test.
